Re: Dynamically update TreeTable model
I have the same problem but with a different tree use case. I'm implementing
a facet search which needs to update the tree after a user selects a tree
node (facet). If I recreate the tree model like you were doing it doesn't
persistent the selection, obviously.
I'm not experienced with Swings trees but I think I may have to implment my
own TreeModel.
Does anybody have the solution for this?

I've finally got this working by extending DefaultTreeState and overriding
the isNodeSelected to calculate the selection based upon the wicket model
containing the data. This makes more sense since the tree's state is
representative of the actual data now!

Re: Dynamically update TreeTable model
Posted by CrocodileShoes <ma...@logica.com>.
Thanks for the info, James. I've read through the api and the tutorial on
the sun site but am not much closer to finding a solution.
Perhaps if I explain the full case somebody might have some advice. I'm
also considering whether a tree is the best structure.
I have a wicket model that wraps up a an object that has all the information
to be displayed in the tree. It's easy enough to build a tree and display
this to the user from this model.
My problem is updating it after a user click. When a node is selected it
triggers a data update from database which updates the object the wicket
model wraps and therefore means the tree is completely different. It's
exactly what happens when you narrow down your searches on an online store
or ebay. So it's not a case of inserting or removing a node or two because
typically the only node that stays the same is the selected one.

You should not recreate the TreeModel and for most cases DefaultTreeModel is
what you want. If you are adding a node, add it with:
http://java.sun.com/javase/6/docs/api/javax/swing/tree/DefaultTreeModel.html#insertNodeInto(javax.swing.tree.MutableTreeNode,%20javax.swing.tree.MutableTreeNode,%20int)
which will notify all the listeners, such as the wicket tree
